Cleanup Python 3 changes

* Rework BrickException to simplify the code. Revert partially changes
  done to port os-brick to Python 3, without losing Python 3
* tox.ini: run py34 tests using the commands of the default test
  environent. All os-brick tests now pass on Python 3.4, so testr test
  runner can be used to run tests in parallel, get the test repository,
* tox.ini: exchange order of py27 and py34 in envlist: py34 must be
  run first to workaround a testrepository bug (see the note below).
* README: give advices on tox/testrepository issues with python 2/3

* Discovery of volumes being attached to a host for many transport protocols.
* Removal of volumes from a host.
Hacking on brick requires python-gdbm (for Debian derived distributions),
Python 2.7 and Python 3.4. A recent tox is required, as is a recent virtualenv
(13.1.0 or newer).
If "tox -e py34" fails with the error "db type could not be determined", remove
the .testrepository/ directory and then run "tox -e py34".
